MAP sensor wiring

Hello all ... first time poster here .....

I have a 2001 Grand AM w/ 3400. A few weeks back it started to intermittenly loose the signal from the MAP sensor to the PCM. Now it has lost it all together. It has 5 volts going into and a reference voltage coming out but its not reaching the PCM.

I need to find out which pin it is at the PCM along with any other information in regards to this anyone has to share.

Thanks,
Duane

Well found the problem .. Green " return " wire was loose at the connection near the alternator

Cool deal, the wiring on the GA's can be very irritating to chase, glad ya found it.
